Distribution Transformer
Distribution Transformer
All transformers with ratings up to 5 MVA and primary voltage class up to 33 kV are conventionally categorized as Distribution Transformers. These transformers are primarily used for stepping down voltage at the end-user level in power distribution networks, ensuring safe and efficient power delivery for residential, commercial, and small industrial applications.
Assured Features
- The highest dielectric insulation property to withstand lightning Impulse.
- Mechanical design to withstand short-circuit forces arising during faults.
- Optimum oven heating under vacuum is required to achieve the desired compression height and maximum insulation resistance (IR) to windings.
- Adequate ducts between layers, coils, and discs for maximum oil flow and reduced hot spot temperature.
- Step-lap designed CRGO laminations for lower losses and excitation current.
- Pre-compressed Insulation material for minimal moisture absorption.
